Croatian Train Manufacturer KONČAR Selects Leclanché as Supplier of Battery Systems for New State Railroad Contract

Thu Apr 13
  • First commercial agreement with KONČAR for two new trains for medium distance transport in both coastline and inland areas.
  • Leclanché to supply its INT-53 Energy packs and battery thermal management systems for one fully electric train, along with one hybrid train
  • Battery-powered trains are significantly more energy efficient compared to diesel locomotives and release no emissions


YVERDON-LES-BAINS, Switzerland 13 April, 2023 – Croatian rail vehicle manufacturer KONČAR Electric Vehicles has turned to Leclanché SA (SIX: LECN) to provide the battery systems for a new high-profile Croatian state railroad contract (click here for images).

Under terms of the initial agreement, Leclanché will supply its INT-53 Energy rail battery system for two trains. KONČAR will be building the trains for HZPP, the state national railway operator. The trains will be BMU (Battery Multiple Unit) and BEMU (Battery Electric Multiple Unit) models for passenger transport on routes surrounding the cities of Varazdin, Osijek, Virovitica and Bjelovar. There is also potential for further use on the routes around Split in the Dalmatian region and around Pula in the Istria.


Together with the railway certified lithium ion (Li-ion) batteries, Leclanché will provide battery thermal management systems and multi-string-managers to allow proper battery cooling, ensuring that different battery strings charge and discharge in parallel and communicate as a single unit to the vehicle control unit. Battery-powered trains provide numerous advantages to travellers, transit operators and the public at large, including quieter operation (some 50% quieter than diesel trains), carbon-free mobility, substantial maintenance savings as well as being an investment in a sustainable future.


Leclanché INT-53 Energy packs

Leclanché’s INT-53 Energy packs are a modular and scalable lithium-ion battery solution for use on trains operating on partially or non-electrified rail routes. The systems are designed to the highest level of safety standards; they are equipped with functionally safe battery management systems (BMS), robust enclosures that mitigate any thermal events and are also IP67-rated against adverse environmental conditions.

Leclanché manufactures the entirety of its battery systems from cell production, through to pack assembly, in its German and Swiss factories. The whole process is certified in accordance with the International Railway Industry Standard (IRIS), a world-renowned global system for the evaluation of companies in the rail sector.

“We turned to Leclanché as battery supplier for several reasons, but most importantly, their focus on safety,” said Gordan Kolak, CEO, KONČAR. The eight-year cycle life of INT-53 Energy packs and their compliance with stringent European railway standards are of vital consideration to us.”

Leclanché will provide 14 of its INT-53 Energy packs for the fully battery-powered train and 12 for the hybrid. It will also provide its dedicated battery thermal management systems.

“We are excited to collaborate with KONČAR on this project and supply our class-leading railroad battery packs to them. Leclanché is looking forward to an ongoing joint commitment to decarbonise the rail industry,” said Phil Broad, CEO, Leclanché e-Mobility. “Our INT-53 rail pack is uniquely designed to meet the rigorous demands of rail manufacturers and operators – everything from cycle life, size, energy, power, safety and charge rate were key requirements in this nomination.”
